Specification of Letters Patent.

Patented sept. 1, 1908'.

Be it known that I, EDWARD A. SANDERS, a citizen of the United States, residing in Oakland, inthe county of Alameda and State of California, have invented new and useful Im rovements in Metal VVindow- Sash, of wiich the following is a specification.

This invention relates to improvements made in the construction of tubular window sashes, and frames for sashes.

It has for its object the production metal window-sash having several features. and advantages that render it especially.

applicable to the production of fire-proof windows, and to windows other than fireproof in which the sashes are adapted to swing as well as to slide.

Thenovel points or features of the invention comprise a construction of tubular bar or rail of sheet-metal having a peculiarly formed groove or recess to admit the glass, and means or devices for fastening the glass in place, the groove ,or recess being formed or produced by bending and lapping the sides of a strip of sheet metal.

The invention embraces further the production of a sheet-metal sash in which the rails and stiles are adapted to permit the glass to .be inserted in place through the rail. Also certain novel construction and combi nation of parts producing an improved metal window-sash, applicable to swinging or slid-- mg windows, or to those having both features or qualities.

The nature of my said improvements, and the manner in which I proceed to produce, apply and carry out the same are explained -at length in the following description in which reference is had to the accompanying drawings forming part thereof:-

Figure 1 of the said drawing is a front elevation of asash for a swinging and sliding window, embodying my invention the members of the sash being broken away in par-t to expose the manner of setting the glass in the sash. Fig. 2 is a similar view of a sash constructed for a window in"\\'hich the sash is adapted to slide, but not to swing in the frame. Fig. 3 is a view of a' portion of a glazed sash removed from the frame, as seen from the outsideof the window, showing one mode of securing the stiles and rails together at the corners. Fig. 4 is a transverse section through the botto1nrail of the sash, with the glass in the groove. Fig. 5 is a tical cross-section through ,the top-rail and 1 bottom. rail'of the lower sash in which the top-rail is provided with a slot for inserting the glass in place from above. Fig. 8 is a top-view of the top-rail showing a portion of the rail partly broken away to disclose the internal construction.v Fig. 9 is a side-view ofa stile provided with a bearing for a pivot; the tube being broken away touncover parts inside. Fig. 10 is a horizontal cross-section through the tube, just above/the line of the pivot.

.In the construction of my improved win- (low-sash the stiles 0r upright members 2 2 and the rails or horizontal members 3-4 are separately formed from a strip of metal of the length and width required for the member, by bending the strip around a mandrel of cylindrical shape, for about three quarters of the circumference, and forming in-the remaining portion, for the entire length of the member a right angle recess 6. Such recess is produced by bending the metal along one side or edge of strip 7 and on or par: lel with a line running diametrically across the cylindrical portion and to, or nearly to, the center; and afterwards at right angles outwardly or towards the circumference, as seen at 8, Figs. 4 and 5, and then bending the opposite edge portion 9 of the metal-strip at right angles inwardly, so as to lie against the outwardly standing edge ortion 8 on the opposite side of the strip, t ereby interlocking the ends of the strip and at the same time producing the recess 6 to receive the glass having two sides only, one side forming a seat for the glass and the other side forming a backing therefor. This recess exceeds in depth the thickness of the glass to be set in the sash, to an extent sufficient to admit a strip 17, whi(-.h is fastened in place over the glass aldng the recess, the same being fastened, in one way, by means of screws inserted through the strip and into the metal behind it; or, in anothcn way, by the use of clips 18 of pliable metal, such as copper, which are readily secured in place in the tribular bar or rail by inserting the same between the overlapping members 8-9 of the joint.

In the'bottom-rail 4 the groove for the glass is similarly formed, excepting that itis a close groove 16 and not open on one side. It corresponds inv width to the thickness of the glass, so asto admit the latter when it is inserted through the top-rail into the grooves of the side-bars. To 'ermitthe in-trodue' tion of the glass from a ove in that manner, the top-rail is formed or provided with a slot or openiri 19extending downward through it and in ine with the gro ove 16 in the side bars, as seen in Figs. 6 and 7, the edges of the slot being usually rounded or turned inwardly to form a close joint between the rail rnd the glass. A slide or movable plate 20 ntted within the hollow rail forms a means of closing the slit or opening in the top after the glass is set in place. a

The means illustrated in Figs. 7 and 8 for closing the opening in the rail is a curved plate 20, fittedon the inside of the tubular rail so as to have a limited movement in an arc in one direction to uncover the opening, and in the contrary direction to close it; the plate being confined in place by pins or screws .21 working in slots 22. This is a simple means of closing theslot in the top rail; but "other means may be employed for the same purpose, such, for'eXa1nple,'as a simple cap or curved strip fastened over the openingfroln the outside. It willbe obvi ous, also, that the strips on the side-grooves to confine the glass in'plaeeniay be permanently secured. to the side-bars where the glass is inserted and set into the grooves from the top of the sash in the above 'ile scribed manner; alsothat eli'p's, putty, and

other means to hold the glass in the sash can be dispensl with to advantage. 7

It will evident that the construction above described is applicable to a double sash, or one having several lights or panes set side by side and separated one from the other by astile or upright-bar. The stiles and 'rails thus formed arejoined together to complete the sash, eitlier'by means of cornerpieces 5 having cylindrical ends or bosses to fit into the ends of the t ubular rails or bars,

as *seen inFigs. 1'.;.d 3. ()r, in anotherway, by letting thef'ends of the top-rail and the bottom-rail intothe side-bars, as seen in Figs. 2, 7 and 8. /The parts thus joined together are fastened by screws or pins insert' ed through the walls of the parts.

. VVhere this invention is applied to the construction of a sash for a swinging and slid-- ingwindow in which the sash is pivotally hung in the window-frame, the face of each side-bar is flattened at the point or part where the pivot 's to be located, and an ear or knuckle 25y aving an eye to admit the pintle 25 is 'fixgdf against the flattened portion, either by screwing the knuckle against such flattened face,- or by inserting the knuckle-piecethrough a slot in the tube and fastening it-on the inside, as seen in Figs. 9

and 10. Blocks 26 secured in like rndnner to the frame, or stationary part inwhieh the sash is arranged to swing, furnish supports for the pivots cZ-e on the upper and lower sashes. U

l/Vherethis construction is applied to or employed in other than, fire-proof windows,

' the formation "of the grooves or recesses be ing well adapted to that purpose. j

Figs. 1 and 3 represent the manner. in which I join the rails and stiles: of the sash together by corner;blocl s. These pieces are each cast preferably in one piece with bosses to fit in the ends ofthe tube; v

ticularly for sashes of large sizesand heavy weight. The cornenpieces can be dispensed with, however, andtfio parts joined at the the stiles, as seen in Figs. 7 and 8. Insueh modification the stiles 2 should be made of greaterdiameter than the rails 35-4, so that the ends of the latter parts e'an'be fitted into the .'openings in the stiles below, or within the ends of those members. The open ends of the stiles are usually closed by a plug or a cap 27 to give abetter finish to the sash. Additional strength can be secured at these joints by inserting pins or "screws through the/parts. v

/'Hav1ng thus described my invention, what I claim asnew and desire to secure by Let'- ,ters Patent is: r, v

1 A window sash comprising a sheet metal tubular rail )I' stile'forme d with a longitudi nal groo e to receive a pane of glass, the

portions of the sheet metal, the opposite edge parts overlapping and arranged to he opposite the edge of the pane, and at right angles to a face of the groove that constitutes a backing for the pane, substai'itially assct forth.v I 2. In awimlow, sash construction, a rail formed of sheet metal'having its opposite longitudinal edges iiiturned and disposed at right anglesto each other whereby is formed a groove having two sides only, one side of the groove forming the seat for the edge of a pane of glass and the other side forming a backing therefor, substantially as set forth.

3. In a window sash construction, a rail longitudinal edges inturned and disposed at right angles to each other whereby is formed a groove having two sides only, one side of the groove forming the seat for the edge of a backing therefor, the said seat portion of the groove being of double thickness of metal, substantially as set forth.

4. Awindow sash composed of tubular to and bottom rails and stiles of sheet-metal, and metal corner-blocks uniting the ends of corners by setting the ends of the rails into groove/ eing formed by. the inturned edge formed of sheet metal having its opposite i pane of glass and the other, side forming a the glass, can be set with cement, or putty; I,

This construction *is adaptedfnore parangles to the said inturned portions, whereby v is ormed a recess or groove and the corner blocks being formed with slots for the cor-' ners of a pane of glass.

5. In a metal sash for a window, a tubular bottom rail havin a glass-receiving groove,

. stiles having-simi ar grooves to admit the glass, and a to -rail having a slot extending through it an longitudinally of the rail in line with the grooves in the stiles and bottom rail, for inserting the glass from above, and

means for closing said slot after the glass is set. I s

6. In a metal sash, a tubular stile having a recess in its front face formed by a flattened depression, and a knuckle-piece having an eye to receive a pintle and a flange on theback by which it is fixed in place within the recess.

In testimony whereof I have signed my' name to this specification in the presence of two subscrlblng witnesses.

EDWARD A. SANDERS.
